Web service for precise neurological EEG diagnosing

DOMAIN
Healthcare
about the SERVICE
Healthcare web service with rich UI for extensive EEG diagnosing. All the diagnoses are made according to the SCOR standard, which is a unified way of describing the state of the patient in neurology. Data filled by doctors and clinicians are converted into a dynamic PDF report of the patient’s study.

challenges
Complex neurological data
Complex list pages with pagination, exhaustive filtering, and sorting options.
Autosaving for the complex forms with instant validation according to the SCOR standard.
Some of the forms that heavily rely on the SCORE rules must be implemented with the optimistic updates approach.
API generated SVG Headmodel injection into the UI.
SVG Headmodel interaction.
PDF report generation with dynamic layout.
Real-time communication between the UI and third-party EEG reader software.

Solutions
and Results
01
SCORE standard rules
Ensure correct implementation. Divide responsibilities across multiple application layers: Databases, API, UI. Data validation on every application layer,data could not proceed if invalid.
image
02
Comprehensive UI
Smart sorting and filtering approaches made it possible to create complex filters based on the ability to combine the conditions with AND and OR conditions.

03
Autosaving process —transparent for the user.
We ensure that auto-saving data is either successfully saved in the DB or rolled back if the request has failed. The request retry strategy was implemented to overcome unstable Internet connections.

04
Instant action-feedback
If the update on the background fails — data is recovered to the latest successful state and the user gets notified.

05
Interactive SVG Headmodel
We guarantee safe injection into the UI, after being generated on the API side. To sanitize the contents we had to: List the specific set of allowed SVG tags and attributes to prevent the potential threat or attack. Attach the event handlers, based on the SCORE rules. Apply optimistic updates handlers to all of the possible Headmodel actions.

06
Flexible PDF report service
Ability to generate different versions of the report layout on demand. Every hospital can get a different layout according to its needs. Or, to even have numerous versions of the layout for maximum flexibility. The content of the report was built with the React components, which were also reused in the main application for the instant Report preview. The report layout is described via JSON file according to the predefined schema blocks.

07
Real-time updates
Only UI-defined messages are accepted, and unknown types of messages are ignored for security purposes. We used SignalR. The doctors and clinicians now can interact with the third-party EEG reader software and get the updates on the SCORE UI in real-time, no page refresh is needed.
